GUYOT SYSTEM

It is one of the most widespread farming systems in Italy: about 35% of the vineyards use it. Also called espalier system, it is characterized by the simplicity of the structure, good ventilation, good exposure of the leaves and a high quality / production ratio; however, during the summer, it needs a large number of green areas.

The Guyot system allows rather dense planting layouts; the vines are planted at distances of 1.3-1.8 meters in the row and 2-3 meters between the rows. The SIKA poles that make up the framework will be 2-2.3 meters high above the ground and about 5 meters apart in the row. There are normally three steel wires and must be positioned respectively at 1-1.2 meters from the ground and the other two at an interval of 40cm between them, with the function of supporting and containing the vegetation. Particular attention should be paid to the SIKA header poles, which must be larger and stronger than the poles used on the row, to better withstand the traction of the wires.

For the Guyot, a mixed pruning technique is used which consists of growing one fruiting shoot and one spur on an 80-100 cm high vine; the first, cut into 6-12 buds, is folded horizontally along the son and provides the production of the year, while the second, brought to two buds, will give rise to two shoots of which the highest will form the fruiting butt speaking following and lower will provide the new spur. At the third year higher outrage is pruned to 6-12 buds, while a lower spur is left to two buds. Of the shoots that will develop from these two buds, the lowest will be pruned as a spur. While the second will be pruned to 6-12 buds and then placed on the lower iron wire. The following year, the shoot that fructified is removed, replacing it with one of the two shoots emitted during the year from the spur; usually the highest shoot is chosen and pruned to 6-8 buds extended horizontally along the first iron wire. The lower shoot will be pruned as usual to two buds to form the new spur. The Guyot It is suitable for soils that are not very fresh and not excessively fertile, in practice for hilly terrain. And I system with mixed pruning, spur and fruiting head, has been very successful and accompanies as a variant also most of the long pruning systems. The simple Guyot differs from other forms because it always has a single spur and a single fruit branch. There are several variants of this important system: double Guyot, simple overturned, double overturned or cappuccina, spurred palmette. Poles for sika vineyard
